Harbour Language Rules — Unified Developer Guide (GPT-Ready)

[Eric Lendvai]

Happy Holidays,

For those who use AI-assisted development, I posted my first attempt at creating a “Harbour Language Rules — Unified Developer Guide (GPT-Ready).”

You can view it here:
https://github.com/EricLendvai/harbour-language-for-ai-training/blob/main/harbour_language_rules.md

The complete list of documented Harbour functions can be found here:

Excellent! thank you Eric 

[Eric Lendvai]

Thank you Juank and Antonio.

It would be so helpful for any of the founders and true senior Harbour developers to review the Harbour Language Rules and let me know if anything should be fixed or expanded.

I don't think we need to compare Harbour to Clipper, VFP and other xBase languages (unless needed for clarity), but ensure we cover all the wonderful modern features Harbour has. 

Thanks for any help, Eric

This is spectacular, and does a lot to make me use Harbour more. I
don't yet know how to train my ollama Small Language Model on your
material, but I'll be researching it.

Thanks for something great!

Thanks Eric.

I'm not sure if it would be helpful to add std.ch with the commands to the rules definition.

A pinch of salt...

Best regards

Which AI coding agents are you currently using?

[Eric Lendvai]

I use ChatGPT 5.2 Thinking Extended (part of the Plus subscription).

I use “Projects” and add the files from https://github.com/EricLendvai/harbour-language-for-ai-training/.

At the start of any chat where I generate or update Harbour code, I paste the contents of “Harbour_Code%20Generation_Policy_prompt.md” at the beginning of the conversation.

Since I am mainly creating tools, I want to stay in control and lead the code development with ChatGPT.

I am currently enhancing Harbour_ORM, including its own RDD to handle all field types supported by DataWharf (PostgreSQL, etc.) and DuckDB integration. At some point, I will release this to my repository.

Harbour_ORM already provides strong support for SQL databases such as PostgreSQL. Once the DuckDB integration is complete, it will also provide local SQL support.
